To all whom z'z may concern.

Be it known that I, BERTIN NORMAN RODDA, a subject of the King of Great Brit- `ain and Ireland, residing at Torrensville, State of South Australia, Commonwealth of Australia, have invented certain new and useful Improvements in Spring Gates and I/Vipers for Seed Wheels, of which the following is a specification.

This invention has been devised in order to improve the grain feed of a seed drill and cause a positive delivery of the seed or grain from `the supply hopper through a smaller and automatically adjustable outlet to the grain funnel Or tube, and in particular to ensure the sowing of the grain more evenly.

It may be applied to that well known type of feed mechanism in which a flanged wheel revolves within a Somewhat funnel-shaped casing and delivers the grain through an opening in the side thereof. Heretofore the wheel has been formed with a number of cross ribs around the inside of the flange and the grain has been carried thereby.

through a passage about the lowest part of the wheel and discharged through an opening some little distance beyond the lowestpartof the wheel that is at a point where the flange of the wheel has risen to a point where the grain falls off therefrom by gravitation. The outlet is comparatively large and allows the grain at times to be discharged in bunches.

The object of my invention is to make possible the use of al smaller outlet which however shall be capable of automaticadjustment or enlargement when such is required.

According to my invention the grain is delivered from the wheel at about its lowest point, the casing is formed with a release feed outlet, and in front of the outlet is an inclined scraper so fixed as to move the grain outwards and over the edge of the wheel whence it falls into the grain tube.

In order that my invention may be clearly understood I will describe the same with reference to the accompanying drawings in which I have chosen to use for illustrating purposes the wellknown type of grain feed as stated above and in which drawings Fig. l is an outside view. a

Fig. 2 is a view showing a vertical section of the casing upon a yplane just outside of the wheel.

F 1g. 3 is a view showing a'vertical section of the casing upon a plane just within the rim of full.

In the drawings A represents the flanged wheel, .but showing `the wheel in wheel and B 'the casing. rThe casing hasa release feed outlet having a resilient upper lip C, which is normally approximately stationary but which will release or yield to abnormal pressure and enlarge should the grain tend to jam iniuthe outlet. The outer side of the outlet may also be made with aerica.'

I lhe grain loutlet is so positioned that the grain is delivered from the wheel at about its lowest point. At all times the release feed outlet and the scraper are subject to constructionalv modifications.

What I claim as my invention is:`

l. In a feeding device for grain drills, a casing having a discharge opening in the side thereof, a feed wheel mounted in the casing, and a spring lip secured to a fixed support vwithin the feed wheel at thedischargey end thereof and having its free end spaced from the inner face of the feed wheel, substantially` as and for the purpose set forth. j Y

2. In a. feeding device for grain drills, a casing having a discharge outlet,`a spring lipv in the outlet for automatically regulating the lsize of the same, a feed wheel mounted in the casing, and a scraper secured at one end and having its free end extending in front of the discharge outlet, said serving to move the grain outward over the wheel and ensure its proper discharge, the lip and scraper having a common point of attachment.

scraper being inclined to the` wheel and grain drills, the
